A poster attached to a fence bears a photograph of the Labor Party leader and Australian Prime Minister Kevin Rudd in Sydney September 6, 2013. Australia will hold national elections on September 7, with opinion polls pointing to a big defeat for the ruling Labor Party led by Rudd. Rudd returned as premier on June 26 after his party dumped Julia Gillard, the country's first female prime minister, due to a prolonged slump in opinion polls. Tony Abbott, who leads the conservative opposition, can take office if he wins just one extra seat in the parliament's 150-seat lower house.
